Claims. (01. 132-41) The subject matter of this invention is a hair curler having complementary hair clamping members about which hair is coiled and held I thereagainst by a swingable loop adapted to interlock with one of the complementary members. From a more specific aspect the invention deals with a hair curler having hair clamping members in the form of a tube and cover, pivotally interconnected by a one piece loop disconnectably associated with the tube forappropriately holding the coiled hair about the complements. In curling devices of the prior art where a wire loop, cover, and tube are employed fulcrum means in the form of a ferrule or rivet is utilized to pivotally secure the tube and cover. In this type of construction the rear ends of the loop were hingedly fastened to the overhanging terminals of the rivet while the front end thereof cooperated to resiliently but disconnectably interposed or caught between the gaps formed pared stock in order to permit the ends of the loop to be appropriately swaged or punched. In both of the cases mentioned, the closed end of the wire loop has means to'interlock with the 'fore part of the tube. When tolerance exists between the rivet and the ends of the tube the complementary interlocking portions of the loop and tube do not properly aline themselves when the fore part of the loop is swung towards the fore'part of the tube and a certain amount of manual pressure is required to slightly deform the loop to permit the latter to snap into interlocking relation with the fore part of the tube.

With a deformed loop, and where play is present the pressure exerted at the interlocking portions of the loop and tube is relatively light because of the tendency of the arms of the loop to spread apart and consequently the loop at times readily disconnects from the tube due to lack of adequate pressure between the interlocking fore parts of the loop and tube. Of course where play or tolerance occurs the loop in eifect 5 wobbles thus lacking rigidity and true alinement. Where the loop is used as the motive force to close the cover and tube its load is necessarily relatively great and hence a relatively heavy wire is employed to form the loop. Even though rel- 10 atively heavy stock is used relatively low interlocking pressure is obtained between the loop and tube since the arms of the loop are under strain and tend to spread apart and hence invariably the fore part of the loop was out of 15 alinement with the complementary interlocking fore part of the tube also setting up a condition requiring manual displacement of the tube in respect to the locking end of the loop to line v the latter up with the tube or in other words 20 with the prior art curlers of the character referred to-certain difllculties were encountered in the matter of positioning the tube relative to the loop to enable the latter to assume a truly alined relation in respect to the tube and at the 25 same time obtain appreciable and adequate pressure between the interlocking portions of the tube and loop when snapped into engagement.

The principm object of the invention is realized in the provision of a simplified but improved 30 curler wherein the disadvantages cited above are obviated in' respect to the matter of properly aligning the loop relative to the tube, in respect to the matter of obtaining the proper interlocking pressure between the forward cooper- 35 ating parts of the tube and loop, in respect to the matter of eliminating lateral play between the rear ends of the loop and its associated cover and tube, and in the matter of obviating undesirable grasping or locking of hair between the rear ends of the loop and contiguous portions of the curler.

The invention has as a specific object the provision of a novel curler wherein a one piece loop is utilized to serve as fulcrum means for pivotally sustaining the cover relative to the loop and wherein terminals of the loop cooperate with spaced sides of the tube to prevent transverse shifting of the loop relative to the tube and cover, thus providing an arrangement in which a loop of relatively light weight stock of relatively increased resiliency may be employed accompanied by relatively true alinement oi the loop relative to the tube whereby the interlocking parts of the loop and cover are under ade- 'quate pressure to prevent accidental disengagein respect to the cover and the latter in respect to the tube and wherein overlapped portions of the inner ends of the loop are appropriately united to permit terminals of the end portions to cooperate with contiguous parts of the tube to permit displacement of the loop substantially in the same plane in respect to transversely disposed and alined hearings in the tube which pivotally supports the inner overlapped portions of the loop.

The invention has as a further object the provision of a simplified hair curler having a loop provided with overlapped portions united on a bias in respect to the alined bearings swingably guiding the loop, the arrangement being such that the loop is a one piece stabilized and relatively balanced member due to parts of the overlapped portions overhanging the axis of the alined bearings.

Other objects, advantages and features of the invention are in part obvious and in part hereinafter more particularly pointed out and for a clearer understanding of the invention attention is directed to the embodiment herein specifically described and shown in the accompanying drawing in which:

Fig. l is a plan view of my improved curler according to the invention shown partly broken away.

Fig. 2 is a front elevational view of Fig. 11.

Fig. 3 is a sectional view on the line 3-3 of Fig. l.

Fig. 4 is a sectional view on the line 4-4 of Fig. 2, and

Fig. 5 is an enlarged view on the line 5--5 of Fig. 2.

The hair curler l includesa perforated slightly tapered tube H, a perforated cover l2 superimposed thereon, a one piece closed loop l3, and a U shaped spring I! cooperating with the rear terminals l of the cover and tube to normally hold the cover closed against the tube as illustrated in Fig. 2.

The tube H is provided with alined but spaced openings or bearings l6 which are in alinement with the spaced openings or bearings II in the cover. These bearings rotatably sustain inwardly turned portions l8 of the bowed arms IQ of the one piece loop l3 which has its forward end contracted to provide lips 20 adapted to resiliently interlock with the sides of the indentations or grooves 2i at the reduced forward part 22 of the tube.

According to the invention terminals 23 of the inwardly turned ends l8 are disposed on a bias or obliquely in respect to the axis of the alined bearings i6 and H in the tube and cover respectively. However the terminals 23 are juxtapositioned and their contiguous sides are united or merged by a suitable welding process being thus fused-together as at 24 but in an inclined fashion transversely of the tube and cover.

It should be noted that each of the terminals. although disposed at an incline extend across the bore of the tube and have their slightly rounded ends. 25' rotatably but closely disposed adjacent the inner sides of the tube.

By this arrangement it is realized that relative transverse movement between the fused and closed terminals of the loop is avoided. It follows therefore that the inner closed ends of the loop in cooperation with the tube maintain the loop in the same plane during the latters rotational displacement relative to the tube and cover. When therefore lips 20 of the loop reach the contracted front portion of the loop both of these lips will strike resilient beads 25 at the same time. with a slight manual pressure applied to the fore part of the tube, lips 20 may be readily snapped over beads 25 and interlocked within indentations 2i. In other words, although the fused terminals 23 may be said to take the place of a rivet in the case of the hair curling devices of the prior art it is also appreciated that these fused terminals serve as an additional and important function by guiding.

the throw of the loop to permit the contracted end of the loop to properly position or aline itself in respect to its complementary interlocking portion of the tube. As previously pointed out, in the prior art curling devices, because of transverse play or tolerance between the fulcrum rivet and loop, the forward locking portion did not properly aline itself. The same defect existed in the matter of hair curlers utilizing the loop for automatically holding the cover and tube in a closed relation.

As a further feature, it will be appreciated that the fused inner biased ends of the loop also constitute means to stabilize and balance the loop during rotation since similar parts thereof extending on either side of the transverse axis of alined bearings l6 and I1 counterbalance each other thus eliminating vibratory reactions in the loop during its displacement by reason of the equalized balancing means of the biased termine-ls.

with the loop swinging in one plane, the lips of the loop are properly alined and conveniently and readily snap into engagement with the contracted end of the tube. Hence the material employed in forming the loop may be of lighter stock of relatively thin wire. Advantage is taken of such lighter stock to obtain increased resiliency at the locking end of the loop thus decreasing the possibility of accidental detachment of the loop from the tube.

By reason of the fused ends of the loop the increased resiliency provided in the loop is maintained and a certain rigidity is imparted in the loop since the fused terminals thereof do not shift or spread outwardly to depreciate the increased interlocking pressure at its contracted or fore part. 7

In operation, the loop is disconnected from the tube and the cover is opened, a portion of hair is interposed between the cover and tube. The cover is closed to clamp the inserted hair. Remaining portions of hair are wound about both the tube and cover. Subsequently the loop is interlocked with the tube to hold the coiled hair in place against the sides of the loop. The coiled hair is left in the curler until it is appropriately set and dried. Thereafter the loop is detached and the coiled hair is removed from the tube and cover.

It is realized that this invention is susceptible to various changes and modifications and is not confined alone to the particular type of hair curler disclosed and consequently it is intended that all matter contained in the above description and shown in the accompanying drawing shall be interpreted as illustrative and not in a ntransverse displacement of I claim:
